Note: A "dummy regulator" is returned by devm_regulator_get()
if the optional regulator is not present in the device tree,

Extra notes:
DSI read tests have been performed with DCS & GENERIC, short & long
commands, on two different panels.
The maximum fifo size (32*32-bit = 128 bytes on stm32) has been
verified too.

Hi Archit, Andrzej, Laurent & Brian,
What is your opinion regarding this patch? Do you have any advice for
handling hw versions?
Do not hesitate to comment.
Many thanks,

Hw older versions support non-alpha color formats derived
from native alpha color formats only on the primary layer.
For instance, RG16 native format without alpha works fine
on 2nd layer but XR24 (derived color format from AR24)
does not work on 2nd layer.

This patchset adds non-alpha color format support taking into
account older hw versions.

Hi Benjamin,
Working on a coming patch (based on the new has_alpha field in fourcc),
I realized that in particular cases (2 layers + "odd" layer sizes)
memory transfers on MCU are greatly improved too if drm buffers are
aligned on 128 bytes : )
So I suggest to cancel this patch.
Then you can

To optimize data transfers, align pitch on 128 bytes & height
on 4 bytes. This optimization is not applicable on hw without MMU.
